CVE-2025-48108 is an authorization bypass vulnerability in Mojoomla School Management affecting versions through 93.2.0. Attackers can exploit misconfigured access controls to gain unauthorized access. This post covers technical details, affected versions, security impact, and mitigation strategies.

CVE-2025-48108 Overview

CVE-2025-48108 is a Missing Authorization vulnerability in the Mojoomla School Management plugin for WordPress. The flaw affects all plugin versions up to and including 93.2.0. An authenticated attacker with low privileges can abuse incorrectly configured access control checks to perform actions reserved for higher-privileged roles. The underlying weakness maps to CWE-862: Missing Authorization.

The vulnerability was published to the National Vulnerability Database (NVD) on August 26, 2025 and tracked by Patchstack. It carries integrity impact without affecting confidentiality or availability, meaning attackers can modify data they should not control.

Technical Details for CVE-2025-48108

Vulnerability Analysis

The plugin exposes functionality that does not validate whether the requesting user holds the required capability or role. Access control checks are either missing or implemented at an incorrect security level. As a result, a user who authenticates with limited WordPress privileges can invoke actions that should be restricted to administrators or dedicated school management roles.

The impact is scoped to integrity. Attackers can create, modify, or delete records exposed by the plugin without affecting confidentiality or availability of the broader site. Because exploitation requires network access and low-level authentication, any registered user on an affected WordPress instance is a potential threat actor.

Root Cause

The root cause is a Broken Access Control pattern classified as CWE-862: Missing Authorization. Plugin handlers accept privileged requests without verifying the caller's capability through WordPress functions such as current_user_can() or without validating a role-specific nonce. The missing checks allow horizontal and vertical privilege escalation within the plugin's feature set.

Attack Vector

Exploitation occurs over the network against the WordPress HTTP interface. The attacker must hold a valid low-privilege account on the target site, which is common on sites that allow self-registration or that provision subscriber-level accounts for parents, students, or staff. No user interaction is required beyond issuing crafted requests to the plugin's endpoints.

No verified public proof-of-concept code is available. See the Patchstack Vulnerability Advisory for the technical write-up and vendor coordination details.

Detection Methods for CVE-2025-48108

Indicators of Compromise

Unexpected creation, modification, or deletion of records in School Management database tables by non-administrator accounts.
WordPress audit log entries showing privileged plugin actions executed by subscriber, student, or parent roles.
HTTP POST requests from low-privilege sessions targeting admin-ajax.php or plugin endpoints associated with School Management.

Detection Strategies

Review web server access logs for repeated requests to School Management plugin endpoints originating from low-privilege authenticated sessions.
Correlate WordPress user role data with action logs to flag actions that exceed the user's assigned capabilities.
Enable a WordPress activity log plugin to capture create, update, and delete events on plugin-managed entities.

Monitoring Recommendations

Monitor plugin version inventory across WordPress estates and alert on installations at or below version 93.2.0.
Alert on new administrator or elevated role creations that occur shortly after low-privilege account activity.
Track outbound anomalies from the WordPress host that may indicate follow-on tampering after unauthorized data changes.

How to Mitigate CVE-2025-48108

Immediate Actions Required

Update the Mojoomla School Management plugin to a version later than 93.2.0 once the vendor publishes a fixed release.
Audit existing user accounts and remove or downgrade accounts that do not require access to School Management features.
Review recent plugin activity for unauthorized data modifications and restore affected records from backup if tampering is confirmed.

Patch Information

At the time of NVD publication, no fixed version is listed in the advisory metadata. Administrators should monitor the Patchstack Vulnerability Advisory and the plugin's official changelog for release notes addressing the Missing Authorization flaw.

Workarounds

Disable the School Management plugin on affected sites until a patched version is available if the functionality is not business critical.
Restrict access to WordPress registration and to School Management plugin endpoints using a Web Application Firewall rule that enforces role-based access.
Apply a virtual patch through Patchstack or an equivalent WordPress security service to block unauthorized requests to the vulnerable endpoints.

bash

# Configuration example: temporarily disable the plugin via WP-CLI
wp plugin deactivate school-management

# Verify plugin status
wp plugin status school-management
